Normally, urine is a slightly yellowish, transparent liquid. Urine is the blood flow through the glomeruli, the blood uric acid, urea, water, inorganic salts and glucose and other substances through the glomerular filtration action, filtered into the renal sac, the formation of the original urine, that is, the predecessor of urine.
The original urine in the body, after being absorbed and utilized again, is left over, and the part that is not absorbed by the human body will form urine and be metabolized out of the body through the excretory organs of the human body.
01
The production of urine is divided into 3 steps
Filtered
When the blood of the human body passes through the human glomeruli, some components of the plasma can be filtered through the glomeruli and then enter the human renal sac.
Reabsorption
The filtered fluid passes through the renal sac and then into the human tubules and collection ducts, where many useful substances are reabsorbed back into the bloodstream.
secrete
The body's tubules and collecting duct epithelial cells secrete components from the surrounding capillaries, as well as some junk toxins produced by these cells themselves, into the renal tubules and collection duct lumen.
There are two kidneys in the human body, and every minute will continue to form green leaves, about 125 ml, which is 180 liters for a whole day, and after kidney filtration, 1 ml of urine will be formed.
So usually try to drink as much water as possible, of course, this process, but also varies from person to person, after sufficient water into the human body, it takes about 5 to 6 minutes of time, the formation of urine metabolism out of the body, if the capacity of the bladder is relatively large, then the time to urinate may be extended.

Do different colors of urine indicate different diseases? Doctors reveal for you: the secret of the color of urine
haematuria
From a medical point of view, there are two types of hematuria:
One is medical hematuria, which is mainly caused by inflammation of the kidneys.
The other is human urinary system bleeding, the most common is urinary tract infection, or the appearance of stone tumors, which may lead to this situation.
But there is a point that needs to be distinguished, if the urine is red, it does not mean that it is hematuria, at this time we must rule out some mistakes or drug reasons, if the urine, the naked eye can see the blood, it is best to go to the hospital in time to check.
Brown urine
The excreted urine becomes brown, most of the time because the bilirubin in the body is tricking, and the amount of bilirubin secreted in the body exceeds a certain limit, which will lead to bilirubin urine.
This situation usually represents that the body's liver has been damaged, affecting bilirubin, there is no way to be normally absorbed by the liver, a large number of red blood cells in the body are destroyed, and brown urine will appear when bile bilebin is inhaled into the intestinal wall.
white
The human body excretes white urine, just like milk, first of all need to understand whether it is the reason for what you usually eat, if your recent diet includes some high-fat foods, then through the adjustment of dietary structure, it will generally recover on its own.
If it is not caused by food, it is best to go to the hospital for examination, especially in the urine, like the milky white of taomi water, and even when there are flocculents floating on the surface, accompanied by frequent urination, urgency, painful urination, poor urination symptoms, it may be that the body has a urinary tract infection or kidney lesions.
Strong brown
Clinical data show that many patients with early hepatitis also excrete such urine, mainly because the liver has the effect of excreting bile to digest food. There are two main channels of excretion in the human body:
One is urine, the other is the intestine, if the human liver or gallbladder has abnormalities, then the passage to the human intestine will be cut off, urine can only be metabolized from the human urethra, in this case, the amount of bile contained in the urine will increase, showing a dark yellow or strong brown color.
Tips
Although different urine represents different diseases of the body, it may also be related to some foods and drugs.
To put it bluntly, the color of the urine has changed, then it means that there are some substances in it, if your body eats some easy food, there may be blue urine, or after using some drugs, there will be blue and black urine, so it is found that the color of the urine has changed, it is best to find the real reason in time.
